-2 to -4C, tending to slightly rise for a time.

Much terrain frozen following overnight frost. Becoming 300-400m perhaps slightly higher into early afternoon.

Planning Outlook

Most mountain terrain is likely to stay frozen throughout the week ahead. Sometimes freezing conditions to lower slopes, although some day-to-day variations. Wind speed and direction will vary considerably, intermittent lulls, but then a deep low is expected to affect Britain by Tuesday-Wednesday, bringing stormy conditions, perhaps widely. Further lows are likely to follow later in the week. Extensive snowfalls possible on the hills, a mix of snow and rain lower down.
